RADIATOR VALVE Filed May 8, 1936 IN VENTOR.

ATTORNEY.

Patented July 20, 1937 omrso sr'res 'FFIE 1 Claim.

This invention relates to valves and more particularly to types adaptedfor use in connection with radiators as installed in buildings forwarming them.

An object of the invention is to provide a valve for steam radiatorsthat will prevent flooding and surging of the condensed steam when thevalve is opened for the passage of steam.

A further feature is in the provision of an escape valve to control theflow of liquid through the system.

Another purpose is to produce a simple but highly efiective valve thatcan be cheaply and economically produced.

These objects are accomplished by the novel and practical constructionand combination of parts hereinafter described and shown in the annexeddrawing, forming a material part of this disclosure, and in which:

Figure 1 is a sectional view taken along the center of an embodiment ofthe invention.

Figure 2 is a top plan View of the self-adjusting element of the valve.

Figure 3 is a side elevational view of the same.

5 Figure 4 is a bottom plan view thereof.

Figure 5 is a side elevational view of a slightly modified form of thevalve, parts being broken away to show the construction.

Referring in greater detail to the drawing, the

body of the valve will be seen to consist of a hollow cylindrical lowerbody portion it: having a contracted inlet 55 provided with threads toengage a supply pipe.

A transverse partition wall I! extends across the body is, above whichis an offset dome l8, surmounted by a cap [9 provided with a stuffingbox 20 for the reception of a packing washer 2i. The cap I9 is axiallythreaded to receive a valve stem 22, its smooth upper portion 23 passingthrough the stufiing box to a manually operable knob 24.

On the lower reduced end of the stem 22 is seat opening 33, contiguousto the valve passage 28 and communicating with the outlet 30.

A support bracket 35 is held within the body l5 by its stem 36 securedby a clamp nut 31.

An upright stem 38 extends from the top of the support 35, and passesthrough a narrow plate 40 fixed on the lower, larger end of a hollowcone 4| closed at its upper end 02 across which is fixed an uprightplate 43, this cone being selfadjustably mounted and adapted to engagethe seat 33.

In the modification shown in Figure 5, a difierent shape of valve body50 is disclosed, and in place of an axial inlet a radial inlet 5! issubstituted, all other parts being substantially as previouslydescribed.

In operation, when under steam pressure, should the valve 25-26, shownin Figure 1, be imperfectly closed or defective, steam will enter theradiator, condensing therein and there accumulating in an excessivequantity of water.

The cone 4i pressed tightly against its seat 33 and held by the pressureof the steam, prevents thesteam from entering the radiator.

If, however, the pressure of the steam is reduced, or closed completelyoff, the cone H becomes automatically disengaged from its seat 33,allowing the water entrained in the radiator toescape, returning to thesteam supply source by its piping, without damage or inconvenience.

While certain preferred embodiments of this device have been shown anddescribed, it will be understood that changes in the form, arrangements,proportions, sizes and details thereof may be made without departingfrom the scope of the invention as defined in the appended claim.

Having thus described theinvention, what is claimed as new and desiredto secure by Letters Patent, is:-

In a radiator valve including a casing having lower and uppercompartments provided respectively with an inlet .and outlet, a valvecontrolled passage between said compartments and a conical openingoffset from said passage, a bracket fixed in the wall of said lowercompartment, said bracket having an upturned cylindrical stud, a hollowself-adjusting conical element alined with the mentioned opening, a barextending across the open base of said element, said bar having anopening slidably fitting said stud, and a guide plate fixed at its loweredge to the apex of said element, said plate being erect and adapted toslidably engage in the mentioned opening.
